allows for a 10 per cent larger area with a 10 per cent shorter wall. As the wall is built on a curve, it is a cheaper wall to build, since it does not require extensive and expensive footings to keep the wall from overturning from water and ground pressures. With this particular shape of pool, there is 25 per cent more wadable

water, that is, water from three to five-feet deep, and is, therefore, much more efficient as regards water depths. Ideal conditions for a swimming pool are 85 per, cent wadable, three to fivefeet deep, and 15 per cent deep water for diving purposes. Obviously that is only possible in large pools because it takes 30 to 40 feet of one end of the pool for the diving pit. So, if you start out with a 60-foot length rectangular pool, and a 30-foot diving area, 50 per cent of the pool area is used for the diving pit which in turn leaves 50 per cent for wadable water. So the Ovoid allows us to approach theoretical standard of 85 per cent wadable water much better and will be about 10 per cent higher than the rectangular pool. Also, this shape pool has the advantage of setting into the landscape a little nicer and adjusts itself to landscaping much better*unless you have very formal arrangements.

Pool Size For Theatres

Letis discuss the size of the pool. We normally figure as We said before that around two per cent of the population will use the pool at any one time and if we assume that there are no other pools in


your community, then we should have a pool to carry that number of people. But, where in Municipal pools, we build for the maximm load, which we figure will happen only 6-10 days per summer; in this theatre pool, we build for the medium load, which should happen* maybe-5O per cent of the time and, therefore, we would cut that figure down to about 1.33 per cent of the population for one-time use. Triple that for daily use, i.e., about four per cent. So, in a private venture of this kind, you could plan on the pool being filled to capacity at least 50 per cent of the time, and, therefore, we would use a much smaller pooh

As indicated above, experience has shown that to take care of a certain number of people we have to have a certain size pool. Pools normally are regulated by various systems. But one used more than any other is that there should be one bathhouse facility per every 10 square feet of shallow water from three-foot to five-foot deep, and one bathhouse facility for every 30 square feet of surface for the deep water. Obviously to build a pool and haVe less bathhouse facilities than the pool will take care of would be poor design.

Using that criterion, and with a population of 10,000 people, we would recommend a pool 50 feet by 75 feet-Ovoid. If it is a town of about 5,000, we would recommend a 40-foot by 60-foot Ovoid pool. For towns of around 15,000, we would recommend a 60 by 90-foot Ovoid pool. For towns of around 25,000 to

ONLY THE largest ozonors would be interested in swimming pools such as the one in Tiff-in. 0.

30,000, we would recommend an 80-foot by 120-foot Ovoid pool. For towns of 60,000 and up, we would recommend the 100-foot by 165-foot International-50 meter*swimming pool. These sizes are all one size smaller than we would recommend for Municipalities of the population given. The sizes given are for Ovoid shapes.

For the rectangular pool, the width should not exceed half the length, preferably even somewhat less; the 165-foot pool should be 75-feet wide, the 120-foot pool, not over 60 feet wide, the 105-foot pool 50-55 feet wide, the 90-foot pool 40-45 feet wide, the 75-foot pool 30-35 feet wide, and the 60-foot pool not over 30 feet wide.

Theatre Pool Equipment

The outdoor theatre pool must have complete pool and bathhouse equipment. Purification equipment comprising filters, sterilizer, pump, motor, chemical pots, etc., must turn over the water in the pool in not more than eight hours. Some States require a six-hour turnover. That is, the water comes in at one end of the pool and goes out the other end in a specialized system of piping at a rate which would re-circulate all of the water in the pool in that number of hours. The water must be sterilized and kept up to a udrinking water standard." In fact, in a great many instances one finds that the water in the swimming pool will test even better than the water you drink as far as bacterial content and clarity is concerned. To the above, the largest single item, must be added the spring boards, ladders, guards-stands, depth signs, swimming lanes, vacuum cleaner, slides-if you like, and other miscellaneous fioating equipment which all adds to the use and pleasure of the bathers. v

In the bathhouse, of course, you can run the gamut of a bathhouse, which isnt and doesnlt do much more than to give you a place to hang a few clothes, provide a place for cleansing showers and a few sanitary facilities, to the complete bathhouse which has a complete sanitary arrangement for both the public and the bathers. Men and women will have locker rooms, dressing stalls for the women, locker benches for the men, vanity shelves, entrance room W with

i counter, restrooms, offices, First Aid

Room, and other miscellaneous bather equipment and areas which the owner might want to put in.

A great many times a concession stand for all kinds of candies, drinks and icecreams and sandwiches are arranged for ealthough it must be said here that none of this food is allowed around the swimming pool itself. State laws do not allow food of any kind to be used around the swimming pool itself. The bather must leave the swimming pool area to buy this food and must eat or consume this food while away from the pool as it cannot be carried back to the pool.
